From the Forbes 400 Richest in America 2004 writeup of Pierre Omidyar:
Former computer programmer launched online auctioneer Ebay in 1995. Today the world's biggest dot-com ($62 billion market capitalization), which lets consumers bid on everything from arcane Americana to Iraqi dinars.
Millions of people buying and selling worthless junk... at least Pierre spends his money to do good. ;)
